Synopsis
This article describes an issue where installing STM software on RHEL Linux 6 and unable to gain access to the admin web ui.
Problem or Goal
After installing the Stingray Traffic Manager software on Red Hat Enterprise Linux 6 default install, there is no access to admin WEB UI.

When running a tcpdump on the Traffic Manager while attempting to connect to the web UI using a browser, the packet trace shows the client req: is TCP over 9090, and the next packet is an ICMP response from the STM to the client:

code: 10 host administratively prohibited message
Unable to telnet to the Stingray Traffic Manager IP:port 9090 from a Windows machine.

Following steps taken:

  1. Turn off ICMP Forwarding Tables - for more information on this step, please see here
  2. Verify there are no firewall exclusions
  3. Verify that port 9090 is open and listening
Cause
Solution
In addition to the above steps, this issue may be resolved by turning off SELinx. The following steps from the RedHat site may be used to verify SELinux status, then use VI or nano to change the status:

Use the getenforce or sestatus commands to check the status of SELinux. The getenforce command returns Enforcing, Permissive, or Disabled.

The sestatus command returns the SELinux status and the SELinux policy being used:

~]$sestatusSELinux status:   enabledSELinuxfs mount:   /selinuxCurrent mode:    enforcingMode from config file:     enforcingPolicy version:   24Policy from config file:  
      targeted

Note: Other Linux software distributions may have SELinux enabled by default.
